Linewidth-tolerant low complexity pilot-aided carrier phase recovery for M-QAM using superscalar parallelization

A modified superscalar parallelization based phase-locked loop combined with the maximum-likelihood algorithm is proposed. Its high tolerance to laser linewidth is demonstrated both numerically and experimentally.
